Abstract
The invention discloses an antistatic PC / ASA (polycarbonate / acrylonitrile styrene acrylate copolymer) alloy plastic for automotive interior trim parts and a method for manufacturing the antistatic PC / ASA alloy plastic. The antistatic PC / ASA alloy plastic for the automotive interior trim parts comprises, by weight, 60-80% of PC resin, 10-20% of ASA resin, 2-6% of toughening agents, 0.3-0.9% of antioxidants, 0.2-0.6% of ultraviolet absorbents, 0.1-0.3% of lubricants, 5-15% of antistatic agents and 0.2-0.6% of chain extenders. The antistatic PC / ASA alloy plastic for the automotive interior trim parts and the method have the advantages that the antistatic PC / ASA alloy plastic is excellent in antistatic performance and mechanical performance, high in strength and good in rigid-tough balance and is heat-resistant, light-resistant and anticorrosion, dust cannot be easily sucked by the surfaces of the antistatic PC / ASA alloy plastic, and the automotive interior trim parts in various shape can be made of the antistatic PC / ASA alloy plastic by means of injection molding.
Description
Technical field [0001] The invention relates to an alloy plastic for automobile interior parts and a preparation method thereof, in particular to an antistatic PC / ASA alloy plastic for automobile interior parts and a preparation method thereof. Background technique [0002] Polycarbonate (PC for short) is a polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. At present, only aromatic polycarbonate has been industrially produced. Due to the special structure of polycarbonate, it has become the fastest growing general engineering plastic among the five major engineering plastics. [0003] ASA (English name: Acrylonitrile Styrene acrylate copolymer) engineering plastic is a graft copolymer of acrylic rub...
